Search sure has come a long way from its blue text link beginnings. While the desktop and mobile versions of Google still offer some of those options there are so many different ways to search now it’s hard for marketers to get their arms around optimizing it all.
Voice search adds a whole new dimension to the discipline and Siri has upped the ante (at least initially as it seems that its Beta tag is proving it should be just that, in beta). The other side of the “new search” has been products like Google Goggles which allows users to take a picture of what they are interested in learning more about then letting Google (hopefully) either identify the object in question and supply additional information about it. I have used the service before and found the need to frame and click an item perfectly was clunky. Now it appears that that has changed.
